Dr. Demento

Barret Eugene Hansen, known professionally as Dr. Demento, is an American radio broadcaster and record collector specializing in novelty songs, comedy, and strange or unusual recordings dating from the early days of phonograph records to the present. Hansen created the Demento persona in 1970 while working at the Pasadena, California, station KPPC-FM. After he once played "Transfusion" by Nervous Norvus on the radio, DJ "The Obscene" Steven Clean said that Hansen had to be "demented" to play it; this event inspired his stage name.
